The novel features of myihventioh tails iiioz'e particularly to the ifor ei: oiently scouring the thing 1'5 of the loop or key-lug i3 andiz'iwardiyextending tmnsve'rse loops 1%- being fully shownend describedin Letters Patent No. 854,985 granted May 28, 190-7 to Seth AfCi-one.

The flange 16 is formed, at about its trans-- verse middle portion,with. an inwardly projeoted tongue 1.? and above and below seid tonguewith vertically elongated slits Whose Walls are preierahly spi'eadoneon;

slits 18 but when the: of the speoial "term and construction shown. anddesorihed herein they i'eoeive portions of the metal of the flange 12and i'iimly unite the flange 16 their m x e 11d spread-slits 18 are forDo. who nlete ii iii miich the book 11 is formed is in its letcondition, said tongue being of dove-toil outliiie at its free endportion. 19 and united with the outer portions of the flange it} by anoutwardly diverging section 20 (Fig. D said tongue thus being connectedWiththe flange 1G by it substantial extent of met-2:1"andcreeting atits'u ppei' and lower edges eneng ulei' forms. tion at the contiguousportions of the parts 1.9, 20 to receive and form a. look with they'east'metel. The plate is out on three ooiineoted lines to fcziii'i.the tongue l; at time when, asabove desorilied, plate in its 1 saidplateat 'war-dly to fol-m the hoxdoop or key-lug 13,

this resulting in theldrawing together, to

' some extent, of the o ening' leftby the cutting and depression thetongue 17, whereby the upper and lower edges of said opening are, asshown in Fig. 1, drawn toward each I other and the opening becomes lessin vertical widflr than the vertical width of the free end portion 19 ofthe said tongue, said portion 19 being,

which it was out after said. upper and lower side edges each other bythe operation of forming the box loop 13.

The cast metal covers the inwardly ro-* 0 ening has its jected'tongue 17and not only forms a ock above and at the edges of said tongue, but

extends above the same and between the upper and lower inner end portionof the tongue and the inner surfaces of the ba ck plate where the latterhas been drawn inwardly at the up er and lower edges of the ipening fromWllCll the tongue was cut.

leaving the upper and lower edge portions of I the tongue extendedupwardly and down' wardly beyond the edge vportions of said opening. Y jI f I have referred to the ton ue 17 as being cut from an interiorportion of the back plate, because said tongue extends in an inwardlydirection from the side edge portion of the plate and does not extendoutwardly through said edge, leaving the edge portion of the plate aboutthe outer end of the tongue 1n its integral condition, which I alsoconsider advantageous. The slits or openings 18,

above and below the tongue 17 are also formed when the metal for theback is flat,

and these slits 18 arecuts through the metal,

none of the latter being removed, and in the finished article become ofspecial character since the outer side wallsof the slits "are pressedoutwardly or s read so as to form concave outlines 21. T. 1e outwardlyspreading (awe side walls of the slits18 results in ,/the"' uter edgesof the flange 18 adjacent to said slits being moved outwardly on convexlines, as at 22. After the slits 18 have been cut and,:1their wallsspread, the flange 16 is arched er curved, as shown in Figs. 1 and 5, tosuitably rece ve the flange 12 of the body 10, and this arching of saidflange results in the edges of the sl t-openings 18 becoming rawntoward.

as shown in Fig. 1, of greater vertical width than the opening fromseton inclined-lines so that they operate as,

beveled surfaces to receiveand lock between them portions of the castmetal, the outer edges of said slit openings being-wider than f theinner edges thereof and the walls of said openings being thereby enabledto effectually. tie the cast metal flange '12 to the flange 16 of theback plate.

I do not wish to limit the invention, in

' everyinstance, to the formation of the, 100k".-

ing openings-18 by first slitting and spreading the metal, as just abovedescribed, and then arching the flange 16 so as.to jform beveled edgesat said openings, but prefer said construction because 'Of itsefliciency and the fact that none of the material of'the back is removedin the formation of said openings. The-body 10 is in one integralcasting and the back 11 in one integral plate and said.

body and back are united together by the cast metal flowing andsolidifying upon the transverse lo0ps,14, beveled edges 15, central lips23, tongue'17 andedges' of the slitopenings 18, the flange portion 16 ofthe back being united'with the flange 12 of the body portion 10 moreespecially by-the' cast metal which engages the-tongue 17 andentersi'the slit openings 18, but. being additionally secured by beingintegral with the main portion of the back plate and the featuresreferred to for uniting the'main portion of the back late to the mainportion of the body 10.

hecentral lips' 23 are created in the forma 'tion of the box-looporkey-lug 13 and are disclosed in my aforesaid Patent No. 854,985.
